什么是PHP等效的PHP函数hash_hmac() [英] What is the .NET equivalent of the PHP function hash_hmac()
本文介绍了什么是PHP等效的PHP函数hash_hmac()的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我将一些代码从PHP移植到.NET(我不是一个PHP开发人员),它看起来很简单,除了以下行:
I'm porting some code from PHP to .NET (I'm not a PHP developer) and it all looks pretty straightforward apart from the following line:
public function hash($message, $secret)
{
return base64_encode(hash_hmac('sha1', $message, $secret));
}
如何将此函数移植到.NET?
How can I port this function to .NET?
base64编码如下,但是如何复制hash_hmac()?
The base64 encoding is done as follows, but how do I replicate hash_hmac()?
Convert.ToBase64String (System.Text.Encoding.ASCII.GetBytes(tmpString));
谢谢!
推荐答案
最后我设法创建一个基于HMACSHA1类的解决方案:
In the end I managed to create a solution based on the HMACSHA1 class:
private string Hash(string message, byte[] secretKey)
{
byte[] msgBytes = System.Text.Encoding.UTF8.GetBytes(message);
byte[] hashBytes;
using (HMACSHA1 hmac = new HMACSHA1(secretKey))
{
hashBytes = hmac.ComputeHash(msgBytes);
}
var sb = new StringBuilder();
for (int i = 0; i < hashBytes.Length; i++)
sb.Append(hashBytes[i].ToString("x2"));
string hexString = sb.ToString();
byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(hexString);
return System.Convert.ToBase64String(toEncodeAsBytes);
}
UPDATED :压缩代码有点 - 对于这么多帮助函数。
UPDATED: Compacted code a bit - no need for so many helper functions.
